Add comment

add_comment

Post a review comment on a project, attributed to "Clueso AI".

Use this to leave feedback, suggestions, or notes — either at the project level (no clip_id) or pinned to a specific clip with an optional timestamp inside that clip.

Pass parent_comment_id to REPLY to an existing comment rather than open a new thread. Read what is already there with get_comments first: answering a reviewer in their own thread is what makes the note resolvable, where a fresh top-level comment just adds noise.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
clip_idNoOptional clip ID to pin the comment to. Omit for a project-level comment.
project_idYesThe project (guide) ID
comment_textYesComment text to post
clip_timestampNoOptional timestamp within the clip (seconds). Only used when clip_id is provided.
parent_comment_idNoReply to this comment instead of starting a new thread. Take the id from get_comments. Replying is how you answer feedback you have acted on — the clip pin and timestamp come from the parent, so leave clip_id/clip_timestamp off.

TDQS

A4.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description goes beyond annotations by disclosing that the comment is attributed to "Clueso AI" (a behavioral trait), and explains the threading behavior: replying makes the note resolvable, while a fresh top-level comment adds noise. It also states that when replying, the clip pin and timestamp come from the parent, so clip_id/clip_timestamp should be omitted. Annotations only provide readOnly/destructive hints, so this added context is valuable.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise (about 120 words), front-loaded with the core action, and organized into logical sections: main purpose, use cases (project vs. clip), and reply guidance. No filler or repetition; every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (5 parameters, no output schema), the description covers the key usage patterns, parameter relationships, and workflow prerequisites (reading with get_comments). It does not describe response/return values or error behavior, which is a minor gap, but overall an agent has enough context to invoke the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

While the schema already documents all parameters (100% coverage), the description adds crucial inter-parameter semantics: it explains clip_id is omitted for project-level comments, clip_timestamp is only used when clip_id is provided, and parent_comment_id should be taken from get_comments and implies leaving clip_id/clip_timestamp off when replying. This is more actionable than the schema alone.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: "Post a review comment on a project, attributed to 'Clueso AI'." It immediately distinguishes from related tools like get_comments by stating its write purpose and clarifying project-level vs. clip-pinned comments.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly says when to use the tool ("Use this to leave feedback, suggestions, or notes"), and provides clear guidance on when to reply vs. start a new thread: "Pass parent_comment_id to REPLY to an existing comment rather than open a new thread." It also directs the agent to read existing comments with get_comments first and warns against adding noise, which is a clear alternative/usage boundary.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
